GdfidL has been used to calculate the resistive wall heating in the vacuum components of the Electron-Ion Collider (EIC). In this paper, we present the simulation results for the beam-induced resistive wake potentials in various vacuum components of the EIC, including the beam screen and the hadron polarimeter in the hadron storage ring (HSR). The resistive wall losses are calculated from the wake potential computed in the finite-difference 3D electromagnetic code GdfidL and compared to the results obtained from the time-domain solver of another 3D electromagnetic code CST.
